You can dissolve iodine more easily in water if you first add some potassium iodide to the water. Then it dissolves more easily. Iodine is I believe a solid at room temperature though.
Also glucose powder dissolves in water because glucose is a very polar molecule (has lots of differing charges in the molecule) and so is water, so they associate easily (attracted due to +/- charges) and glucose becomes dispersed throughout the liquid i.e. dissolved.

Hmm - hard question, since iodine in its solid form will instantly turn straight to a gas.
There is no such thing as liquid iodine at STP by the way...

Iodine does not dissolve well in water, it dissolves better in organic solvents such as alcohol. However, a small amount will dissolve in water, forming iodine water. See the website below.

No, iodine does not react with water. It is not soluble in water, but is soluble in alcohol.
